Nonstop flight route between Napa, California, United States and Shemya, Alaska, United States:

About this route:

A direct, nonstop flight between Napa County Airport (APC), Napa, California, United States and Eareckson Air Station (SYA), Shemya, Alaska, United States would travel a Great Circle distance of 3,128 miles (or 5,034 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Napa County Airport and Eareckson Air Station, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Napa County Airport and Eareckson Air Station. You'll see that it will travel the same route of the red line on this map!

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• During 2008 the airport's 1960-era control tower received extensive radio, plumbing and electrical upgrades and renovations funded by the federal government.
• In addition to being known as "Napa County Airport", another name for APC is "Napa Army Airfield".
